Episode narrativeepisode_narrativeA strong upper level trough of low pressure extending from the Intermountain West into the Four Corners Region energized the southwest flow aloft across the Southern Plains during much of the day on May 8th, with a strong low level jet sustaining a mesoscale convective complex (MCS) across much of Oklahoma into Northcentral Texas south into the Texas Hill Country. While these storms gradually weakened after daybreak as a cold pool from these storms propagated southeast into the region, additional upper level disturbances ahead of this trough interacted with ample moisture and instability near this cold pool to intensify these showers and thunderstorms, some of which became severe with damaging winds as they moved across portions of East Texas, Southwest Arkansas, and North Louisiana. Strong low level shear was also present within the moderately unstable air mass, with discrete supercell thunderstorms developing across extreme East Texas and North Louisiana. This resulted in several reports of tornadoes, with two separate tracks found across Northern Harrison and extreme Northeast Panola Counties, before the storms moved into North Louisiana by mid-afternoon. Locally heavy rainfall from the stronger storms within a short period of time also resulted in localized flash flooding across portions of Cass County, with flash flooding also reported across Eastern Harrison and Panola Counties during the early morning hours on May 9th as additional showers and thunderstorms redeveloped and moved repeatedly over the same areas. During the evening hours on the 9th, isolated severe thunderstorms developed over portions of Deep East Texas along old outflow boundaries from the storms earlier in the day. These storms produced large hail in extreme Southern Sabine County and Central Nacogdoches County before diminishing by midnight.
